I still want to discuss Skip Columns
As real example, Excel sheet contains following data:
!screenshot-1.png!
QueryRecord fails on the column B which doesnt have a name with NPE. Skip
columns in ConvertExceltoCSV allows to skip this column.
One more good thing about ConvertExceltoCSV - Include Header Line property. Or
we will be forced for each file provide a schema?

> Issue Type: New Feature
> Components: Extensions
> Reporter: David Handermann
> Assignee: Daniel Stieglitz
> Priority: Minor

> A new Excel Record Reader should be implemented to support reading XSLX
> spreadsheet rows as NiFi Records. This Reader will enable integration with
> various record-oriented components, obviating the need for the narrowly
> focused ConvertExcelToCSVProcessor. The initial version of the Excel Reader
> should not support the legacy binary XLS format.
> The ExcelReader should use a library that supports reading from a stream of
> rows to avoid consuming large amounts of heap memory during processing.
> The ExcelReader should support configurable properties to read selected
> sheets. With Excel supporting typed field values, some amount of field type
> mapping will be required. Additional input filtering properties should not be
> implemented as existing Processors like QueryRecord support a wide variety of
> filtering and projection use cases.
